(1 Market St, East Paterson, NJ.)Filed July 5, 1962, Ser. No. 208,630 21 Claims. (Cl. 83-341) Myinvention relates to winding machines and more particularly to webwinding and treating machines, this application being acontinuation-in-part of my copending applications Serial No. 747,909,filed July 11, 1958, now abandoned, and Serial No. 118,892, filed June22, 1961, and now abandoned.

In the fabrication of toilet paper or tissue rolls, it has been thecustomary practice to employ a web winding machine to wind paper webabout a core to constitute an elongated or major roll for subsequenttransverse severing to form relatively short or minor rolls of toilettissue. Perforating means is also employed and arranged between thepaper supply roll and the core station to form the web with spaced rowsof transversely extending perforations defining therebetween sections ofpaper of uniform lengths for detachment from the minor rolls byseverance along the lines of perforations. Heretofore, in a machine ofthis character, numerous difficulties and disadvantages have beenexperienced in the winding of the major rolls because the web, which ismaintained in a somewhat taut condition to effect uniform winding, isoften torn or partially severed along one or more lines of perforations,by reason of the taut condition of the web coupled with the fact thatthe entire length of each line of perforation is formed simultaneously,with the result that it is necessary to arrest the web feeding operationof the machine, remove the partially wound core, condition the free endof the web for engagement with another core, and then initiate windingof the web about the core.

My invention overcomes the foregoing difficulties and disadvantages, itbeing one of the objects of my invention to provide means fortransversely forming aligned perforations or slits in the web in amanner to overcome the aforementioned tearing and partial severing and,in addition, facilitate removal of the sheets or sections fro-m thetissue rolls along lines of perforations without tearing of the marginalareas of the sheets as is often the case in ordinary perforated rolls.

Another object of my invention is to provide means of the foregoingdescribed character for perforating the paper web with spaced transverselines of openings or slits and which means is effective for forming, ineach line, the outermost slits at the sides of the web one in advance ofthe other with the intermediate slits being formed therebetween inprogressive order from one outermost slit to the other whereby topreclude severing or tearing of the web through slits and/or theadjacent margins of the web during winding of the latter about a core.

A further object of my invention is to provide a slit forming orperforating mechanism for a paper web where in a movable component isequipped with longitudinally extending means having a surfacetransversing the web and progressively engaging, throughout the lengthof said means, the surface of another component angularly disposedrelative to said means and with one of the surfaces being formed withspaced lands to effect spaced lines of transverse perforations in theweb passing between said surfaces.

A still further object of my invention is to provide a slit forming orperforating mechanism for a paper web equipped, in one form of theinvention, with rotatable blade means having longitudinally extendingteeth for transversing the web and progressively engaging, through-3,073,196 Patented Jan. 15., 1963 out the length of said means, thearcuate surface of an abaxially disposed anvil to effect spaced lands ofperforations in the web passing between said means and said anvil and,in another form of the invention, to provide the rotatable blade meanswith longitudinally extending web engaging surfaces, in lieu of teeth,for progressively engaging the arcuate surface of an angularly disposedanvil form with spaced lands to form said perforations.

An important object of my invention is to provide components, such asblades and sections of the anvil, which are readily replaceable andadjustable with a minimum of labor and time.

Another important object of my invention is to provide a slit forming orperforating mechanism of the foregoing described character capable ofbeing incorporated within winding machines already in use withoutappreciable modification and which mechanism is simple in construction,durable in use, efiicient in operation, and economical in maintenance.

With the above and other objects in view, as will hereinafter appear,the invention consists in the combination and arrangement of partshereinafter set forth and illustrated in the accompanying drawings fromwhich the several features of the invention and the advantages attainedthereby will be readily understood by those skilled in the art.

In practicing my invention, as illustrated in the drawings, I provide awinding machine having spaced side frames 1 in which are journaled apair of transversely extending rear and front paper-web guide rolls 2and 3, respectively, for guiding a paper web W from a supply mu 4 to acore winding device equipped with a pair of rolls 5 which engage the weband effects winding thereof about the core 6 in the usual manner to forma major paper roll R for transverse severing into relatively short minorpaper rolls S of toilet tissue, the core, in operation, being carried ona demountable mandrel 7. Also mounted within the frames 1 is a tensionroll 8 for applying tension to the Web W and a spreader roll 9 as isusual in machines of this character. Inasmuch as the foregoing describedcomponents of the machine constitute no part of the present inventionper se, a more detailed description thereof is not believed necessary,suffice to say that said components are only diagrammaticallyillustrated and operate in conjunction with other components notillustrated to feed the web W from the supply roll to the core windingdevice for winding about the core 6.

Interjacent the guide rolls 2 and 3 and in accord with my inventionthere is rotatably journaled in the frames 1 the trunnions or sectionalshaft 11 of a transversely extending rotating member, beam or roller 12having its peripheral face formed with a pair of oppositely disposedlongitudinally extending slots 13 with one side face defining each slotbeing formed with a seat 14 for accommodating thereon the rear face ofthe inner portion of a set of alignedperforating blades 15 extendingsomewhat tangentially and beyond the periphery of the roller '12. Eachset of blades 15 is provided with an outwardly projecting sectionextending from the member 12 and having an outer margin or web engagingsurface formed with web penetrating portions or means comprising aplurality of aligned spaced teeth or lands defined by grooves, said webpenetrating portions constituting a component of web perforating means.Blade clamping means is disposed in each of said slots 13 and includes abar 17 fixed therein by screws 13. The bar 17 thus secures the innerportions of the blades 15 Within the slot 13 in clamped relation withthe seat 14 as clearly illustrated in the drawmgs.

Suitably attached to the frames 1 and extending transversely over themember 12 is a beam or yoke 26 having a lower incurvated flange 21disposed in confronting relation with the member 12, the curvature ofthe lower face of the flange 21 being generated from substantially thesame axis as the peripheral surface of the member 12. Subjacent theflange 21, there is provided a plurality or set of longitudinallyextending rollers 22 having blade engaging portions and coactingtogether to form an anvil having a web engaging surface or zone alsoconstituting a component of the aforementioned web perforating means.The anvil extends over the member 12 with the axes of the rollers 22being disposed in abaxial relation with the axis of the member 12. Therollers 22 are slightly disaligned relative to each other and have theirends connected together in a manner to insure unitary rotation oftherollers and with one of the outermost rollers having an end portion 23extending beyond the yoke and equipped with a pulley 24 connected by adrive belt 25, having crossed runs, to a similar pulley 26 mounted onthe shaft 11 of the member 1?; whereby the roller 12 and the anvil 22rotate in opposite directions at the same linear speeds in accord with apre-established timed relation, the shaft ll being connected to anddriven b suitable gearing G from a power source (not shown). t is to benoted that while the rollers 22 are slightly disaligned relative to eachother, their blade engaging portions lie substantially equal distancesfrom the axis of the member 12 for insuring engagement with the webpenetrating portions of the blades 15 as hereinafter more fullydescribed.

Each of the rollers 22 is journaled within a pair of holders 2'7equipped with threaded shanks 23 extending into the flange 21 andsecured in fixed relation therewith by means of upper and lower nuts 29and 3%, respectively, threaded on the shanks 25. Each of the shanks 28has sleeved thereon subjacent the flange 21, a washer 31 constructed ofcompressible material, for example, leather, and which washer is engagedby the lower nut 36 and thereby clamped between the lower nut 53 and theflange. Each of the holders 27 is formed on its under face with anarcuate groove 32 for accommodating and retaining therein a roller 22with one side of the groove being defined by a removable wall 33normally secured in fixed relation with the opposite wall of the holderby means of a screw 34 or the like. This construction permits therollers 22 to be removed from the holders for replacement and to effectassembly thereof. The holders are each provided with a lubricatingopening 35 extending through the shank 28 to permit lubricant to besupplied to the groove 32 whereby the roller 22 therein is lubricatedfor rotation.

As the member 12 rotates, each of the blades of each set will engage theanvil and inasmuch as the latter is disposed abaxially with respect tothe member 12, the outer tooth of an outermost blade will engage theproxi mus roller 22 of the anvil in advance of the other teeth of theblades with the other teeth progressively engaging the anvil throughoutthe length of each blade during rot-ation of the member 12, it beingunderstood that the outer teeth of each blade have only sufiicientbrushing or wiping engagement with their respective roller 22 to effectperforation of the Web and with the central teeth of the blades having agreater degree of engagement with the anvil by reason of the respectiveroller being disposed in angular relation with the member 12. As new orre placement blades are secured to the member 12, the com tral portionof each blade will engage the anvil to a greater degree than therespective ends and due to the rotational power of the member 11.2 willbe forced under the respective roller and thus perforate the web. It isto be understood that after sufficient wear has occurred between theblade and the anvil substantially the same degree of engagement willobtain throughout the length of each blade. Furthermore, due to thecompressibility of the leather washers 31, the rollers may move slightlyupwardly with the holders to thus permit passing of the blades under theanvil without injury to the blades. In this connection, and withreference to FIGURE 9, it will be assumed that the anvil extends at anangle of 3 relative to the axis of the member 12 as indicated by theline A, whereby, due to the travel of the web at a speed commensuratewith that of the anvil and member 12, there is formed lines ofperforation V in the Web extending at right angles to its line of travelas denoted by the line L. Obviously, as the web travels to the core 6from the supply roll 4, it passes between the member 12 and the rollers22 with the result that each blade engages the web and travels with itto the anvil where the teeth of each blade progressively penetrate theweb, as each tooth engages the anvil, thereby, per-- forating the Web inthe form of spaced slits of a size and shape defined by the teeth asshown in FIGURE 9. An example of the relative positions of the endmostand intermediate rollers 22 of the anvil with respect. to the end andcentral blades of a set is clearly illustrated in FIGURES 6, 7, and 8,it being understood that the same number of blades are provided for thesame number of rollers 22. As viewed in these figures, one of the endblades is disclosed as engaging an end roller of the anvil (FIGURE 6)while an intermediate blade is shown (FIG- URE 7) as approaching anintermediate roller of the anvil. In the same position of the member 12,the other end blade is shown in approaching position to the other endroller (FIGURE 8) to effect final engagement of the blades of therespective set with the anvil. The holders 27 are adjustable relative tothe flange 21 to dispose the rollers 22 at a desired angle relative tothe axis of the member 12 with the ends of the rollers being spaced atgreater distance from the peripheral face of the member 12 than theircentral portions thereby forcing the blades under the rollers 22intermediate their ends as heretofore described.

In the modified form of my invention, as illustrated in FIGURES 11 to 21of the drawings, the transversely extending rotating member or roller 42has its peripheral face formed with a pair of oppositely disposedlongitudinally extending slots 43 with the rear faces defining the slotsreceiving thereagainst the rear faces of somewhat elastic strips 44extending throughout the length of the slots and constituting brakes orcushions accommodating, against their front faces, the inner portions ofblade means comprising sets of aligned perforating blades 45. Each setof blades 45 extends somewhat tangentially and beyond the periphery ofthe roller 42 and is provided on its outer margin with an anvil or webengaging surface 46. Blade clamping means is disposed in each of saidslots 43 and includes a bar 47 fixed therein by screws 48. The bar 47thus secures the inner portions of the blades 45 within the respectiveslot 43 in clamped relation with the cushion 44 as clearly illustratedin the drawings.

Suitably attached to the frames 1 and extending transversely over themember 42 is a beam 50 having a lower flange 51 provided with an underface disposed in confronting relation with the member 42. Subjacent theflange 51, there is provided a plurality of longitudinally extendingcomponents or cylinders 52 constituting an anvil extending over themember 42 at an angle of approximately three degrees relative to theaxis of the member 42 and the longitudinality of the blades 45 asdepicted in FIGURES 16, 17, and 18, the axes of the cylinders 52 beingalso disposed in abaxial or angular longitudinal relation with the axisof the member 42. The cylinders 52 are slightly disaligned relative toeach other and have their ends disposed in somewhat abutting relation asshown in the drawings. Each cylinder is formed with spacedcircumferentially extending lands 53 defining therebetween grooves orslots 54 and with the lands 53 providing a blade engaging surface 55 forengaging the surfaces 46 of the blade means.

Each of the cylinders 52 is journaled within a pair of holders 57equipped with threaded shanks 58 extending into the flange 51 throughopenings 59 and secured in fixed relation with the flange 51 by means ofupper and lower nuts 66 threaded on the shanks 58. Each of the holders'7 is formed with a head 61 provided on its under face with an arcuategroove 62 for accommodating and retaining therein the ends of cylinders52 with one side of the groove being defined by a removable wall 63normally secured in fixed relation with the opposite wall of the holderby means of a screw 64 or the like. This construction permits thecylinders 52 to be readily replaced, assembled and/or circumferentiallyadjusted, when maintained in a fixed position, to compensate for wear.The openings 59 are so arranged in the flange 51 that the shanks 58 maybe suitably adjusted relative to the flange to dispose the heads 61 inproper position for receiving the cylinders 52. The holders 57 are eachprovided with a lubricating opening 65 extending through the shank 58 topermit 6 lubricant to be supplied to the groove 62 whereby the cylinders52 therein may be lubricated for rotation.

It will be apparent that due to the angularity of the anvil relative tothe blades and the uniform projection of the latter from the member 42,each of the blades, when rotationally engaging the lands 53 of acorrelated cylinder 52, will be subjected to a progressively increasingstress from its leading end (FIGURES 16 and 19) toward its intermediateportion (FIGURES l7 and 20) and thence to a progressively diminishingstress towards its trailing end (FIGURES 18 and 21). During engagementof the blades and cylinders, the brakes will respond to stress variationby permitting a slight cushioning of the blades away from the anvil tocompensate somewhat for the variation in stress and thereby provide asubstantially smooth running, brushing or wiping engagement of theblades with the cylinders without any damage thereto and/or rupture to aweb passing therebetween, it being understood that a slight flexing ofthe blades may also contribute to the smooth running engagement of thecomponents. In some instances, a relatively slight wear imparted toeither the blades or the cylinders will sometimes relieve some of thestress until such time as the cylinders or blades are replaced.

In the forms of the invention herein disclosed, when the machine isoperated and the web W fed from the supply roll 4 to the rolls 5 of thewinding device and between the anvil and blade means, the latter, duringrotation, will perforate or form slits in the web by penetrating and engaging the cylinders and in a manner wherein the slits or openings ineach line of perforations are progressively formed from one side of theweb to the other. When thus formed, the slits define transverse lines ofperforations or openings V disposed in right angular relation to thedirection of the web travel L as previously noted in connection withFIGURE 6, the angularity of the anvil relative to the axis of rotationof the blade means being indicated by the broken line A.

In actual reduction to practice, a plurality of winding machines havingbeen equipped with my invention, I have found that the positioning ofthe anvil in angular relation to the longitudinality of the bladesproduces a highly satisfactory result in that the transverse lines orperforations, progressively formed, enables the machines to be operatedat greater speeds without rupture of the web as is usually inherent inthe operation of prior art machines. In the operation, the member (whichmounts the blades) rotates at a speed commensurate with that of thelinear speed of the web W to thus preclude any tearing of the web duringperforation thereof.

Furthermore, a paper web treated by my invention will be provided withtransverse rows of perforations -in the form of spaced slits or openingswhich facilitate detachment of sections of toilet tissue from each otheralong the lines of perforations and without tearing or rupturing themarginal areas of the sections as would be the case wherein theperforations in each line were simultaneously formed incontradistinction to being progressively formed during longitudinaltravel of the web. It is to be understood that the term perforation andits declensions, as herein set forth, shall be construed in theirbroadest sense and be inclusive of slit, score, opening, and cut andtheir respective declensions.

Without further elaboration, the foregoing will so fully explain theinvention that others may, by applying current knowledge, readily adaptthe same for use under various conditions of service. Moreover, it isnot indispensable that all the features of the invention be usedconjointly since they may be employed advantageously in variouscombinations and subcombinations.

It is obvious that the invention is not confined solely to the useherein disclosed in connection therewith as it may be utilized for anypurpose to which it is adaptable. It is therefore to be understood thatthe invention is not limited to the specific construction as illustratedand described, as the same is only illustrative of the principlesinvolved which are capable of extended application in various forms, andthe invention comprehends all construction within the scope of theappended claims.
